- Abstract
Background: Magnetic resonance image-guided high-intensity-focused ultrasound (MR-HIFU) is a rather new, noninvasive option for the treatment of uterine fibroids. It is safe, effective, and has a very short recovery time. However, a lack of prospectively collected data on long-term (cost-)effectiveness of the MR-HIFU treatment compared with standard uterine fibroid care prevents the MR-HIFU treatment from being reimbursed for this indication. Therefore, at this point, when conservative treatment for uterine fibroid symptoms has failed or is not accepted by patients, standard care includes the more invasive treatments hysterectomy, myomectomy, and uterine artery embolization (UAE). Primary outcomes of currently available data on MR-HIFU treatment often consist of technical outcomes, instead of patient-centered outcomes such as quality of life (QoL), and do not include the use of the latest equipment or most up-to-date treatment strategies. Moreover, data on cost-effectiveness are rare and seldom include data on a societal level such as productivity loss or use of painkillers. Because of the lack of reimbursement, broad clinical implementation has not taken place, nor is the proper role of MR-HIFU in uterine fibroid care sufficiently clear. Objective: The objective of our study is to determine the long-term (cost-)effectiveness of MR-HIFU compared with standard (minimally) invasive fibroid treatments. Methods: The MYCHOICE study is a national, multicenter, open randomized controlled trial with randomization in a 2:1 ratio to MR-HIFU or standard care including hysterectomy, myomectomy, and UAE. The sample size is 240 patients in total. Women are included when they are 18 years or older, in premenopausal stage, diagnosed with symptomatic uterine fibroids, conservative treatment has failed or is not accepted, and eligible for MR-HIFU. Primary outcomes of the study are QoL 24 months after treatment and costs of treatment including direct health care costs, loss of prod

- Abstract
Objective: The aim of this study was to compare the effect of ulipristal acetate (UPA) and gonadotropin-releasing hormone agonists (GnRHa) before laparoscopic myomectomy on long term secondary outcomes of the MYOMEX-trial, regarding quality of life, ultrasound characteristics, hemoglobin levels 6 weeks post-operative, sexual function and menstrual bleeding control. A cost-analysis was also performed. Short-term primary and secondary outcomes are reported elsewhere. Study design: A double-blind, randomized, controlled, non-inferiority trial in nine hospitals in the Netherlands. Participants were randomized in a 1:1 ratio (block size of four, stratified per hospital) to either UPA or GnRHa pre-treatment. Additional placebo injections containing saline, respectively daily placebo tablets were given to both groups to ensure double-blinding. Surgery was performed within a month after the last tablet. Women were followed up until six months post-surgery. Results: A total of 55 participants were randomized: 30 to the UPA- and 25 to the GnRHa-group between May 2015 and July 2017. Uterine volume at six weeks post-operative did not differ significantly between both pre-treatment groups with 170.1 cm3 (106.8–243.5; N = 29) vs. 152.8 cm3 (92.3–205.6; N = 23) for the UPA- and GnRHa-group respectively (p = 0.423). Hemoglobin levels six weeks post-operatively recovered back to baseline and were not significantly different between groups with 7.7 mmol/L for the UPA- vs. 8.1 mmol/L for the GnRHa-group (p = 0.157; mean difference -0.4 (CI -0.9, 0.2). Menstrual bleeding pattern, quality of life, effects on general and sexual health showed a significant improvement compared to baseline in both groups without any differences between the treatment groups. Symptom severity scores also decreased significantly at 6 week post-operatively compared to baseline, but did not differ between the treatment groups. Fibroid characteristics at baseline (e.g. mean

- Abstract
Purpose: Since the introduction of minimally invasive gynecologic surgery, the percentage of advanced laparoscopic procedures has greatly increased worldwide. It seems therefore, timely to standardize laparoscopic gynecologic care according to the principles of evidence-based medicine. With this goal in mind—the Dutch Society of Gynecological Endoscopic Surgery initiated in The Netherlands the development of a national guideline for laparoscopic hysterectomy (LH). This present article provides a summary of the main recommendations of the guideline. Methods: This guideline was developed following the Dutch guideline of medical specialists and in accordance with the AGREE II tool. Clinically important issues were firstly defined and translated into research questions. A literature search per topic was then conducted to identify relevant articles. The quality of the evidence of these articles was rated following the GRADE systematic. An expert panel consisting of 18 selected gynecologists was consulted to formulate best practice recommendations for each topic. Results: Ten topics were considered in this guideline, including amongst others, the different approaches for hysterectomy, advice regarding tissue extraction, pre-operative medical treatment and prevention of ureter injury. This work resulted in the development of a clinical practical guideline of LH with evidence- and expert-based recommendations. The guideline is currently being implemented in The Netherlands. Conclusion: A guideline for LH was developed. It gives an overview of best clinical practice recommendations. It serves to standardize care, provides guidance for daily practice and aims to guarantee the quality of LH at an (inter)national level., Medical Instruments & Bio-Inspired Technology
